IMPROVEMENT IN DRYING AND PREPARING CRUCIBLES.

Specification forming part of Letters Patent No. 48,713, dated July 11, 1865.

4 sey City, in the county of Hudson and State of New Jersey, have invented a newand Improved Mode of Drying and Preparing Crucibles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. The nature of my invention consists in placing the crucibles on carriages at the cool end ot'a flue and gradually forwarding them toward the fire, where they are prepared and ejected, the usual method being to inclose them in a tire-clay vessel after having been dried, then prepared in the usual way potters do their waresviz., in a kiln. Figure 1 is an end elevation through the firelace- Fi .2 an end elevation of the carria e Fig. 3, a plan of one-half the same.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct a flue of any suitable material,

The flue maybe made any desirable length and another placed 011 top, as shown at F, Fig. 1.

G is the furnace, between the dotted lines under the floor-level, built of bricks in the usual way and fed at the side through the opening, B being the doors. The projections E are understood to be extended outside the flue, so as to run the carriages out or in, as required,

I fill a carriage, L, with crucibles K, (shown by dotted lines,) and placeit in the fine, farthest end from the fire, then others in succession, which graduallybrings the first over the fire, where they are properly reddened, then pushed out for the next to take its place, and so on indefinitely.

ally moving them from the cool part ofa flue toward the fire, either inside or outside said flue, on a carriage, or shifted by hand.

2. The construction of a flue,in combination with carriages, as described, and for the purpose specified.
